iOS 27.3 Beta 1 Brings Redesigned Health App and iPhone Duo Tweaks

A redesigned Health app

The new Health design first appeared in iOS 27.2 testing but did not make that final release. It is organized into three sections: Insights, Longevity and Browse. The layout adapts dynamically to a user's data and draws on Apple Intelligence.

The Longevity section adds a feature called Health Age, which uses Apple Watch data to compare a user's health indicators with their actual age. Owners of the Apple Watch Series 12 and Apple Watch Ultra 4 get easy access to a Readiness Score each morning.

Apple Fitness+ gains Gym Strength, which creates progressive four-week plans based on a user's strength goals, experience, schedule and available equipment. Plans adapt as you train: after each week, the next one is adjusted according to the repetitions and weights the user logged.

iPhone Duo and StandBy

The iPhone Duo gets Reachability, which moves the outer display's interface to the left or right for one-handed use. Users swipe right at the right edge of the screen or left at the left edge. The keyboard also changes slightly, with narrower keys and a smaller font.

Apple is also bringing the enhanced StandBy mode introduced with the iPhone Duo to all iPhone models. It includes redesigned analog and digital clock faces, more options for colors and on-screen elements, and support for Shared Albums in the Photos face.
